ssd1306 and ssd1331 oled

Hello, I have a ssd1306 i2c oled I followed this guide, https://learn.adafruit.com/ssd1306-oled-displays-with-raspberry-pi-and-beaglebone-black/usage everything works fine. I also have a 96x64 spi ssd1331 oled. I followed the same guide, except I use this line git clone https://github.com/adafruit/micropython-adafruit-rgb-display.git instead. When I ran the ssd1331.py example, it says import utime importError No module named utime. How do I itall this utime? Do I need to install MicroPython Thanks
